• Interface bridging in high-speed digital communication networks
• Temporary data storage in embedded processing architectures

FIFOs Memory Procurement Notes

This component has been officially discontinued by the manufacturer. Verification of end-of-life status is required before integration into new designs. Sourcing is restricted to existing stock or secondary markets. Compliance documentation indicates non-RoHS status for this specific variant. Engineers must validate lead times and authenticity through authorized distributors when procuring remaining inventory units.

FIFOs Memory Selection Notes

Designers should evaluate alternative components due to the discontinuation status of this part. Considerations include verifying pin compatibility and electrical specifications against newer generations within the same family. Ensure that the 128-pin TQFP footprint matches the target PCB layout constraints. Confirm that the 3.3V operating voltage aligns with the system power rails and that the 10ns access time meets the application's throughput requirements.

FIFOs Memory Part Context

The 72V3643L15PF8 belongs to the 72V series of synchronous FIFO memories manufactured by Renesas Electronics. This series provides high-performance data buffering solutions for complex digital systems. The specific model utilizes a 128-lead Thin Quad Flat Package, distinguishing it from other variants in the lineup that may offer different pin counts or packaging styles such as the 120-pin TQFP found in related models.
